BOOSTXL-BATPAKMKII: BQ24250 fast charge on BOOSTXL-BATPAKMKII

Part Number: BOOSTXL-BATPAKMKII

Hi

I just gotten a BOOSTXL-BATPAKMKII eval board and have a question on charging in standalone mode.

The default Riset (R4) and Rilim (R1) are configured at 500ohm and 270ohm respectively.

I am trying to get the eval board to fast charge at 2A an dhad changed the resistors to

Riset (R4) = 130 ohm, around 1.92A

Rilim (R1) =135ohm, 2A limit

Power supply = connected a 5V/2A PSU from a workbench PSU TTI model 

But when I connect a 3.7V Lipo battery (4000mAH) to it, the current drawn from the workbench PSU is only 500mA.?? 

Have I missed out something that I have not changed to charge the battery in standalone mode?
